Things God cares about: beards, pews, organs, and head-coverings. They are, if I understand the Fathers correctly, primarily what the Incarnation, Life, Death and Resurrection of Our Lord was about. Ultimately, fallen man needed to know what customs were to be taken on by God's people. Salvation, eternal destiny, the paths of our lives, these are what hang in the balance. So let us remember to keep the main things the main things.
In the words of the Apostle Paul, "Finally, brethren, whatever is coarse and curly, whatever furnishes our naves, whatever accompanies our singing, whatever adorns our noggins, think on these things."
